工作时间(时) | 0 | 1 | 2 | 3 | 4 | 5 |
加工数量(吨) | 0 | 0.5 | 1 | 1.5 | 2 | 2.5 |
(1)把上表中相对应的点描在下图中,再顺次连接。
(2)工作时间与加工数量成什么比例?为什么?
(3)现在碾米8吨,需要几小时?

y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x, x∈[–1,1], y∈[–π/2,π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
